Hi there,,,these are the settings that I had set up on the gps but when i put in new coordinates it didnt take me to the exact spot about fifty or so metres out,, i have since been told that these settings are for new zealand marine maps,,, so it has all puzzled me....cheers Bo
You always need to match the datum of whatever map you are using, so if you are using an NZ datum map you must set the GPS to that datum before pluging in the maps coordinates. Most all maps will reference what datum they use somewhere on the map. WGS 84 is a global datum and the newest in use, so generally that is what is used at other times. For the correct datum you can select the datum (hit enter when it is highlighted on the 12) from a large list of choices in the 12. You see it. It is New Zealand something or other.
